It belongs on an indoor PCB in office equipment, appliances, or test gear. Do not spec it into an engine bay, outdoor telecom cabinet, or factory floor where ambient could dip below freezing. Frequency stability is ±50 ppm — tight enough for a 1.8432 MHz reference driving an MCU clock input or a UART without external trimming. For a -40°C environment you would need the industrial-grade variant in the DSC1030 family. ## Standby power-down and package fit The output goes high-Z in standby, so the downstream clock input needs a pull-down or the MCU's internal weak pull to avoid floating. 4-SMD no-lead package, 5.00 mm x 3.20 mm body, 0.90 mm seated height — a standard footprint shared by many MEMS and quartz oscillators. The land pattern matches the common 5.0×3.2 mm oscillator pad layout; no via-in-pad required.","metaTitle":"DSC1030BC1-001.8432 MEMS Oscillator 1.8432 MHz CMOS XO","metaDescription":"Active Microchip DSC1030BC1-001.8432 MEMS XO, 1.8432 MHz, CMOS output, 3V supply, 0°C~70°C, ±50ppm stability, 3mA max.
